Description

Technical Field

[0001] This invention belongs to the field of waterway safety patrol technology, specifically referring to an unmanned vessel integrating waterway safety patrol monitoring and rescue. Background Technology

[0002] Patrols of rivers, lakes, reservoirs, coastal areas, and flood-affected waters often rely on manual boat operations, which present challenges such as difficulties at night, high personal risks to on-site personnel, slow response times to emergencies, and blind spots in waterway inspections. In the event of a drowning incident, ground rescue personnel often take a long time to reach the scene, easily missing the crucial window for rescue.

[0003] The existing unmanned surface vessels (USVs) that integrate waterway safety patrol, monitoring, and rescue have the following problems: Existing unmanned vessels with dual inflatable pontoons have weak resistance to wind, waves, and water flow disturbances, making it difficult to maintain stability during close-range rescue operations. In inland river environments with wind and waves, continuous river flow, and turbulent flow during the flood season, the hull is easily affected by water flow, causing it to drift and sway laterally. When the hull approaches a person in the water, water flow disturbances will continuously cause the hull to sway, making it difficult to maintain a stable operating distance and posing a safety hazard of colliding with the person in the water. Meanwhile, traditional dual-inflatable pontoon unmanned vessels cannot work in conjunction with drones, which greatly reduces the efficiency of search and rescue operations for people who have fallen into the water. In summary, it cannot meet the current demand for unmanned vessels that integrate waterway safety patrol, monitoring, and rescue. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, the present invention provides an integrated unmanned vessel for water safety patrol monitoring and rescue, which has strong resistance to wind and waves and water flow disturbances, can stably maintain the hull attitude during close-range rescue, and can dock and link with the unmanned vessel in the event of an emergency to improve the efficiency of rescue operations.

[0005] The technical solution adopted in this plan is as follows: This plan proposes an integrated unmanned surface vessel for water safety patrol monitoring and rescue, including a pontoon hull, a monitor, a propulsion unit, a stabilization and damping mechanism, and an airflow assist mechanism. The monitor is installed on the upper surface of the pontoon hull, and the propulsion unit is installed on one side wall of the pontoon hull. The stabilization and damping mechanism includes a guide assembly, a drive assembly, and a downward damping assembly. The guide assembly is fixedly installed on the upper wall of the pontoon hull, the drive assembly is slidably mounted above the guide assembly, and the downward damping assembly is connected to the bottom of the drive assembly. The airflow assist mechanism includes a docking and sealing assembly, a flow guiding assembly, and an air-driven propulsion assembly. The docking and sealing assembly is located on the upper surface of the drive assembly, the flow guiding assembly is arranged below the drive assembly, and the air-driven propulsion assembly is connected and installed on the side wall of the flow guiding assembly.

[0006] As a further preferred embodiment of the present invention, the guide assembly includes a guide sleeve, a guide post, a limiting plate, and a guide spring; multiple sets of guide sleeves are fixedly arranged on the upper surface of the pontoon hull, and the guide post is vertically slidably assembled inside the guide sleeve; the limiting plate is fixedly installed at the top of the guide post away from the pontoon hull; the guide spring is fitted on the outside of the guide sleeve and the guide post, with its two ends respectively abutting against the limiting plate and the upper surface of the pontoon hull; The drive assembly includes a drone landing platform, a drive electromagnetic plate, and a fixed magnet; the drone landing platform is fixedly installed on the top of multiple guide columns; the drive electromagnetic plate is vertically inserted through the landing platform; the fixed magnet is fixedly installed on the upper surface of the monitor's pressure-bearing shell, and the drive electromagnetic plate and the fixed magnet are arranged vertically opposite each other.

[0007] The downward damping assembly includes a water-pressing connecting rod, a damping mounting frame, and downward damping cylinders; the water-pressing connecting rod vertically penetrates the hull of the pontoon and its top end is fixedly connected to the bottom surface of the guide column; the damping mounting frame is fixedly assembled at the bottom end of the water-pressing connecting rod, and multiple sets of downward damping cylinders are evenly arranged at the bottom of the damping mounting frame; Preferably, the docking sealing assembly includes a docking sleeve and a sealing ring; multiple sets of docking sleeves are vertically opened through the surface of the machine platform, and the sealing ring is embedded in the upper end face of the docking sleeve; The flow guiding assembly includes a flow guiding one-way valve, a gas collecting annular box, and a flow guiding connecting pipe; the flow guiding one-way valve is sealed and connected to the bottom of the docking sleeve, the gas collecting annular box is fixedly arranged on the lower side of the landing platform, and the two ends of the flow guiding connecting pipe are respectively connected to the flow guiding one-way valve and the gas collecting annular box.

[0008] The air propulsion assembly includes an air supply duct, a jet nozzle, and a positioning slide. The upper end of the air supply duct is connected to the bottom of the air collection annular box, and the jet nozzle is sealed and connected to the outer end of the air supply duct away from the air collection annular box. The jet nozzle is arranged in the same direction and parallel to the propeller on the side of the float hull. The positioning slide is fixedly installed on the side wall of the float hull, and the air supply duct is vertically slidably engaged inside the positioning slide. Specifically, a controller is installed on the upper surface of the pontoon hull.

[0009] The controller is electrically connected to the monitor, the thruster, and the drive electromagnetic plate to achieve remote unified electrical control.

[0010] When in use, the operator remotely sends operation instructions to the controller, which then activates the monitor and the propulsion unit respectively. The propulsion unit drives the pontoon hull to sail on the water surface, while the monitor collects images of the water area in real time and transmits the video signals to the remote control terminal through the controller, enabling real-time monitoring of the water area around the clock. The pontoon hull is equipped with a drone landing platform on top, which can carry drones to carry out simultaneous air and water security monitoring of the water area; a towing rope is installed at the stern of the pontoon hull, with a lifebuoy attached to the end of the rope, so that the lifebuoy can be carried along with the hull while it is sailing. When the monitor or airborne drone detects a person falling into the water, the operator remotely controls the propulsion device to drive the pontoon boat toward the waters where the person is in the water and drops a lifebuoy to carry out the rescue. To prevent the hull from drifting and becoming unstable due to water flow disturbance, the controller synchronously controls the drive electromagnetic plate to be energized. After being energized, the drive electromagnetic plate generates a magnetic field different from that of the fixed magnet. The fixed magnet is installed on the upper surface of the pressure-bearing shell of the monitor, and the two attract each other by magnetic force. The electromagnetic attraction force overcomes the elastic force of the guide spring, causing the guide column to slide downward along the guide sleeve. The guide column simultaneously pulls the bottom water-pressing connecting rod and the damping mounting frame to sink as a whole. The downward pressure damping cylinder is immersed in the water, and the underwater damping effect generates downward ballast resistance, suppressing the hull from drifting and yawing, thus stabilizing the hull and enabling the float to resist turbulent currents and accurately reach the rescue area to promptly deploy lifebuoys to people in the water.

[0011] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution adopts a combination of stabilization damping mechanism and airflow assist mechanism to achieve air-water coordinated operation of UAV and unmanned vessel; the pontoon hull carries the UAV for synchronous cruise through the landing platform, the UAV completes large-scale water area patrol from the air, and the pontoon hull conducts close-range detailed monitoring from the water surface.

[0012] After a fall into the water, the drone lands on the landing platform and completes a sealed docking. The drone's rotor continuously delivers downward-washing airflow, which is then transported through the docking sleeve and guide pipe to the underwater jet nozzle. This high-pressure airflow is then sprayed into the water to provide auxiliary propulsion for the pontoon hull, compensate for the navigation resistance generated by the downward-pressure damping cylinder entering the water, and increase the rescue navigation speed while ensuring the stability of the hull, thus significantly improving the efficiency of rescuing people who have fallen into the water.

[0018] like Figures 1-9As shown, the proposed solution provides an integrated unmanned surface vessel (USV) for waterway safety patrol monitoring and rescue, comprising a pontoon hull 1, a monitor 2, a thruster 3, a stabilization and damping mechanism 4, and an airflow assist mechanism 18. The monitor 2 is fixedly installed on the upper surface of the pontoon hull 1, and the thruster 3 is mounted on one side wall of the pontoon hull 1. The stabilization and damping mechanism 4 includes a guide assembly 5, a drive assembly 10, and a downward damping assembly 14.

[0019] The guide assembly 5 includes a guide sleeve 6, a guide post 7, a limiting plate 8, and a guide spring 9; multiple sets of guide sleeves 6 are evenly fixed on the upper surface of the pontoon hull 1, and the guide post 7 is vertically slidably assembled inside the guide sleeve 6; the limiting plate 8 is fixedly installed on the upper end of the guide post 7; the guide spring 9 is fitted on the outside of the guide sleeve 6 and the guide post 7, and the two ends of the spring abut against the limiting plate 8 and the upper wall of the pontoon hull 1, respectively.

[0020] The drive assembly 10 includes a drop platform 11, a drive electromagnetic plate 12, and a fixed magnet 13. The drop platform 11 is fixedly installed at the top of all the guide columns 7. The drive electromagnetic plate 12 vertically penetrates the plate surface of the drop platform 11. The fixed magnet 13 is fixedly assembled on the upper surface of the pressure-bearing shell of the monitor 2, and the drive electromagnetic plate 12 and the fixed magnet 13 are arranged facing each other vertically.

[0021] The downward pressure damping assembly 14 includes a water-pressing connecting rod 15, a damping mounting frame 16, and a downward pressure damping cylinder 17. The water-pressing connecting rod 15 vertically penetrates the hull 1 of the pontoon and is fixedly connected to the bottom surface of the guide column 7 at its top end. The damping mounting frame 16 is fixedly assembled at the bottom end of the water-pressing connecting rod 15, and multiple sets of downward pressure damping cylinders 17 are evenly arranged at the bottom of the damping mounting frame 16.

[0022] The docking sealing assembly 19 includes a docking sleeve 20 and a sealing ring 21; multiple sets of docking sleeves 20 vertically penetrate the surface of the machine platform 11, and the sealing ring 21 is embedded and fixed on the upper end face of the docking sleeve 20.

[0023] The flow guiding assembly 22 includes a flow guiding one-way valve 23, a gas collecting annular box 24, and a flow guiding connecting pipe 25; the flow guiding one-way valve 23 is sealed and connected to the bottom of the docking sleeve 20, the gas collecting annular box 24 is fixedly arranged on the lower side of the landing platform 11, and the two ends of the flow guiding connecting pipe 25 are respectively connected to the flow guiding one-way valve 23 and the gas collecting annular box 24.

[0024] The air propulsion assembly 26 includes an air supply duct 27, a jet nozzle 28, and a positioning slide 29. The upper end of the air supply duct 27 is connected to the bottom of the air collection annular box 24, and the jet nozzle 28 is sealed and connected to the outer end of the air supply duct 27. The jet nozzle 28 is arranged in the same direction and parallel to the propeller 3. The positioning slide 29 is fixedly installed on the side wall of the float hull 1, and the air supply duct 27 is vertically slidably engaged inside the positioning slide 29.

[0025] A controller 30 is fixedly installed on the upper surface of the pontoon hull 1; the controller 30 is electrically connected to the monitor 2, the propeller 3, and the drive electromagnetic plate 12 respectively to realize remote centralized control.

[0026] In practical use, the operator remotely sends control signals to the controller 30, and the controller 30 activates the monitor 2 and the propeller 3 respectively. The propeller 3 drives the buoy hull 1 to sail on the water surface. The monitor 2 collects video images of the water area in real time and transmits the monitoring data to the remote control terminal through the controller 30 to realize real-time visual monitoring of the water area. The pontoon hull 1 is equipped with a landing platform 11 as a drone take-off and landing platform, which can cooperate with drones to carry out joint air and water security patrols. The stern of the pontoon hull 1 is towed by a rope, and the end of the rope is tied to a life ring. The life ring can be carried along with the hull during the voyage. When the monitor 2 or the drone it carries detects a person falling into the water, the drone lands on the upper surface of the landing platform 11. The bottom of the drone is pre-equipped with an organic magnetic sheet for positioning and adsorption. Water flow disturbance can easily cause the pontoon hull 1 to drift, making it unable to stably dock at the rescue point. At this time, the operator remotely controls the controller 30 to activate the drive electromagnetic plate 12, which operates synchronously in two separate paths: The first stabilizing action: The driving electromagnetic plate 12 is energized to generate a magnetic field different from that of the fixed magnet 13. The fixed magnet 13 is installed on the upper surface of the pressure-bearing shell of the monitor 2. The two are attracted to each other by magnetic force. The attraction force overcomes the elastic force of the guide spring 9 and pulls the guide column 7 to slide down along the guide sleeve 6. The guide column 7 drives the damping mounting frame 16 to sink through the water-pressurizing connecting rod 15. The downward pressure damping cylinder 17 at the bottom of the damping mounting frame 16 is completely immersed in the water. The ballast resistance generated by the underwater fluid damping is used to suppress the hull drift and yaw, so that the float hull 1 resists the turbulence and accurately reaches the rescue area to quickly throw life rings to the people who have fallen into the water. The second drone locking action: After the drive electromagnetic plate 12 is powered on, it simultaneously attracts the bottom magnetic plate of the drone, and stably locks and fixes the drone on the landing platform 11. During the overall sinking of the landing platform 11, the air supply duct 27 is simultaneously driven to slide downward along the positioning slide 29, and the jet nozzle 28 is completely submerged below the water surface. After the UAV is locked onto the landing platform 11, the bottom of the UAV rotor is precisely aligned and fitted with the docking sleeve 20. The lower end face of the rotor presses against the sealing ring 21 to form a sealed air passage. The UAV rotor continues to rotate, generating a downward high-pressure airflow. The airflow enters the guide one-way valve 23 through the docking sleeve 20. The guide one-way valve 23 prevents water from flowing back into the pipeline. The airflow flows through the guide connecting pipe 25 into the air collection annular box 24, and then is delivered to the jet nozzle 28 through the air supply duct 27. The jet nozzle 28 sprays high-pressure airflow underwater, providing auxiliary forward thrust for the pontoon hull 1, compensating for the navigation resistance caused by the lowering damping cylinder 17 entering the water, and increasing the navigation speed while ensuring the stability of the hull attitude, thus shortening the rescue arrival time. The operator continuously adjusts the power of the thruster 3 remotely through the controller 30 to drive the pontoon hull 1 to approach the person in the water, drop a life ring, and the pontoon hull 1 pulls the person in the water toward the shore to complete the rescue operation. After the rescue operation is completed, the operator controls the drive electromagnetic plate 12 to be de-energized and demagnetized through the controller 30. The guide spring 9 releases its elastic reset force, and the guide column 7 is pushed to slide upward along the guide sleeve 6 through the limit plate 8 to reset. The damping cylinder 17 is lifted off the water as a whole, the drone is released from the magnetic lock and resumes free take-off and landing. The pontoon hull 1 resumes the normal cruise operation mode. Subsequent operations can repeat the above operation process.
